Senescence. It’s a beautiful-sounding word whose tones suggest it should be a perfume or an essential oil. But that’s not ...

Over 130 mammal species can delay embryonic development, giving their offspring the best possible chance of survival in ideal ...

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the ...

Human embryonic stem cells (HESC) can potentially generate every body cell type, making them excellent candidates for cell- and tissue-replacement therapies. HESC are typically cultured with ...

Embryonic stem cells (ESCs) are stem cells derived from the undifferentiated inner mass cells of a human embryo. Embryonic stem cells are pluripotent, meaning they are able to grow (i.e. differentiate ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly.

BEIJING, Dec. 30 (Xinhua) -- Chinese researchers have developed an in vivo embryonic mouse intrauterine imaging technique, which has elucidated the dynamic process of brain development in embryonic ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

Maternal effect genes produce mRNA or proteins that accumulate in the egg during oogenesis. We show here that Mater, a mouse oocyte protein dependent on the maternal genome, is essential for embryonic ...

One reason cancer is not considered a single disease but many is that every cancer cell seems to be dysfunctional in its own way. Random mutations in a cell’s DNA initiate its slide into abnormal ...
